Science
In August 2012, Voyager 1 recorded a sudden surge in galactic cosmic rays while the surrounding magnetic field barely changed direction—an unexpected combination that revealed the boundary of interstellar space was more complicated than scientists had predicted.
Science
NASA is keeping Voyager 1 alive by switching off instruments and heaters one by one—but it cannot let the spacecraft become so cold that its fuel lines freeze. If those lines fail, Voyager could lose the thrusters that keep its antenna aimed at Earth, permanently silencing the most distant human-made object.
Exo Worlds
In June 2026, the James Webb telescope read the dawn and dusk skies of WASP-121b separately and found one side hotter and stripped of water, the other cooler and possibly cloudy, on a world where it can rain liquid rock
Exo Worlds
We assumed water had to be delivered to planets by comets or asteroids — but a 2025 Nature study found that sub-Neptunes, the most common type of planet in the galaxy, can forge their own oceans by reacting hydrogen atmospheres with molten rock deep inside their cores
Technology News
On July 9, 2026, OpenAI opened its most powerful system yet to the public — GPT-5.6, in three tiers named Sol, Terra and Luna — alongside an agent it calls ChatGPT Work, built to carry out whole jobs rather than merely answer questions

Titan has rivers, rainfall, lakes and a slow hydrological cycle exactly like Earth's, except that every drop of it is liquid methane and the rock the rivers run over is water ice
Psychology
We tend to think loneliness is about having no one around, but the Harvard Study of Adult Development points to something more precise: it is not the absence of people but the absence of people who actually know you — a distinction that can leave someone surrounded and completely alone
Science
Scientists painted black cows with white stripes to test whether zebra markings deter biting flies — and the painted cows drew 50 per cent fewer flies, adding weight to the theory that zebras evolved their colouring not for camouflage or heat, but as a living insect repellent
Science
Earth's magnetic field has flipped hundreds of times, the last reversal was around 780,000 years ago, and the field has been weakening for the past two centuries
Science
A supermassive black hole called RBH-1, weighing at least ten million Suns, appears to have been flung from its galaxy and is now racing through space at nearly 1,000 kilometres per second, leaving a 200,000-light-year wake of newborn stars
Deep Space
Astronomers believe the Milky Way may contain billions, perhaps even trillions, of rogue planets drifting without close stars — and a 2026 study found one 9,800 light-years away that was likely born in a planetary system before being thrown into the dark
Mind & Meaning
In the Viking Age town of Birka, Sweden, a warrior buried with two horses, a sword, an axe, arrows, two shields, and a full set of game pieces was assumed for nearly 140 years to be a man — DNA confirmed in 2017 that the warrior was a woman
Science
In 1859, the Carrington solar storm sent currents surging through telegraph wires, shocking operators, igniting telegraph paper and allowing some lines to transmit with their batteries disconnected. A comparable storm today could cause widespread blackouts—and one influential worst-case assessment warned that full recovery might take four to ten years, although experts remain divided over how severe the damage would actually be.
Space Scopes
In July 1962, a single missing hyphen in the guidance code of NASA's Mariner 1 probe sent it veering off course seconds after launch, forcing range safety officers to destroy a Venus mission that had cost roughly $18 million — a typo Arthur C. Clarke later called the most expensive in history.
